Please don't invent new ways to call programs using subprocess - use the
existing wrappers in the base Plugin class and the utilities module.  

For this use you probably want Plugin.get_command_output() (just test
the 'status' value stored in the returned dictionary).

There's no need for shell=True here and using a shell can introduce
unwanted security and behavioural consequences - this is a main reason
for using the provided interfaces in plugin code.

We don't use camelCase for local identifiers in sos - suggest
'have_usb', 'usb_available' etc. instead.

Ack.

Should be no problem merging this with those few items taken care of.
